FLOUR BINAND SIFTER.i

SPECIFICATION forming part of Letters Patent No. 411,671, dated September .24, 1889. Application filed May 25, 1889.V Serial No. 312,084. (No model.)

To @ZZ whom it may concern/f Be it known that I, JOHN A. MCCLELLAN, a citizen of the United States, residing at Hic-o, in the county of Hamilton, State of Texas, have invented certain new and useful Improvements in 'Flour Bins and Sifters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to a combined flour or other cereal bin and sifter, the main object of the invention being the provision of a combined bin and sift-er, the former being adapted to hold a sack or more of flour, and when it is desired to obtain for use a finelyscreened quality of flour it is only necessary to open the doors on the under side of the screen-frame and operate the sifter.

Another obj ectis to provide means attached to the sifter by which it may be secured to a wall or other place, thereby placing it out of reach of rats, roaches, &c.

Still another object .is that the sifter can be quickly and easily put together and taken apart when it is desired to be cleaned, the whole being capable of manufacture at a minimum cost.

Other objects and advantages of the invention will appear in the following description and the novel features thereof will be particularly pointed out in the claims.

` Referring to the d rawi ngs, Figure 1 is afront elevation of a bin and sifter combined constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section on the line x m of Fig. 1, and Fig. 4. is a perspective of the screen-frame and its doors.

Like letters of reference refer to like parts in all the figures of the drawings.

A is a bin or receptacle, preferably constructed of sheet metal, and is provided with the lid or cover A', the saine in turn having a suitable bail or handle, as A2. Soldered or otherwise suitably attached to the rear wall of the bin arethe anges or wings A3, which are perforated, as at A, for the reception of screws or other fastenings by which the bin may be attached to the wall or other place where itis desired to be used. About midway the bin the rear wall thereof is sloped at a suitable angle or incline, as at A5. The bottom of the bin in this ease is dispensed with and the side walls thereof are extended downwardly to nearly a point, as at A6, and are recessed, as at A7,the function of which will be hereinafter apparent. On the front and rear sloping Walls of the bin there are suitably attached sleeves AS.

B is the screen-fra1ne7 the end walls of which are at their lower ends rounded or curved and connected by the side Walls B', said frame being adapted to receive the concave screen B2, which is suitably secured therein. walls of the frame B are recessed, as at B3, to form a suitable bearing for the journal of the sifter and to perinit them to embrace the lower end of the bin. Suitably attached to the side walls B are sleeves BSX, similar to those A8 on the bin A.

Hinged, as at B", to the screen-frame are the quarto-cylindrical doors B5, one of which preferably overlaps the other or is provided with a flange B, to prevent the escape of flour or the entrance of dust and dirt when the de vice is not in use. The doors B5 are represented by dotted lines in Fi g. 2 as partly opened.

Within the screeirfraine B and at a suit able distance apart are arranged the two disks C, which are connected by the bars C', the whole forming what may be termed a skeleton cylinder. The disks C are further secured to and connected by the shaft C2, which is extended at both ends, so as to be j ournaled in the recesses B3 in the screen-fra1ne B. On one end of the shaft C2 the same is further extended to form a suitable crank O3, by which the cylinder is rotated. XVhen in place the shaft of the sifter is further engaged by the recesses A7 on the bin A,the whole forminga free and easy bearing. The rods C are projected slightly beyond the periphery of the disks G, and should abut freely against the screen B2.

rlhe frame B is fastened to the bin A by the two-pronged pins D, the prongs of which pass through the sleeves As and BB on the bin and screeirfraine, respectively, the heads of the pins being preferably in opposite directions, so that the same cannot pull apart unless the pins are Withdrawn. Any other suitable connecting device, however', may be used.

The operation of the invention is as follows: Flour or other cereal havingbeen put into the The end:

TOO

bin and a quantity of finely-screened flour is desired kfor household purposes, the'flour is pressed downward by its own Weight into the sloping end of the bin and into the screenframe and within the skeleton cylinder. The doors of the screen-frame are then opened, the hand at the same time revolving the crank C3, thus screening the onr by the successive passage of the rods over the screen. The screened flour falls into a suitable receptacle placed there for its reception.

What I claim is- 1. A bin provided with a door or lid and having sleeves secured to said bin at opposite sides, and screening and sifting mechanism provided with similar sleeves, and twopronged pins for connecting the screening and sifting mechanism to the bin, substantially as specified.

2. A bin having sleeves secured thereto at opposite sides and removable screening and sifting mechanism provided with similar sleeves, and two-prong pins engaging said sleeves for connecting the sifting and screening mechanism to the bin, the said pins being arranged with their heads in opposite directions, substantially as and for the purpose specified.

3. A screen-frame having recessed and curved end walls and quarto-cylindrical doors hinged thereto upon opposite sides thereof, with their adjacent edges overlapping, substantially as speciiied.

4. A screen-frame provided with recessed end walls connected by side walls having sleeves thereon, quarto cylindrical doors hinged to said frame, and sifting and screening mechanism arranged within the screen, combined with a bin having like sleeves and removable prongs engaging said sleeves to detachably hold the screen-frame to the bin, substantially as specified.

In testimony whereof I ax my signature in presence of two witnesses.

JOHN A. MCCLELLAN.
